Abstract

The invention discloses a steam generator, comprising a preheater (1), an evaporator (2) and a superheater (3), wherein the preheater (1) is connected with the evaporator (2) by a heat source pipeline and a waterway pipeline; the evaporator (2) is connected with the superheater (3) by a heat source pipeline and a water pipeline; the evaporator (2) comprises an upper separator (4) and a lower separator (5); an evaporator floating head (10) is arranged behind the lower separator (5); an end socket (11) is arranged on the elbow part of the evaporator floating head (10). On the basis of combining with solar thermal power generation heat-carrying working medium physical property, the elbow part of the evaporator is modified, the space at the tail end is enlarged, and the risks of heat source working medium evacuation and solidification are solved.

Description

technical field [0001] The invention relates to a steam generator and belongs to the technical field of solar thermal power generation systems. Background technique [0002] The steam generator is an important equipment in the solar thermal power generation system for the heat exchange between the heat-carrying medium and water to generate steam. The heat source can be molten salt, heat transfer oil or other heat-carrying medium. [0003] In the process of evacuating the heat source and working medium of the evaporator, when the temperature of the heat source decreases, in the tube bundle design of the conventional evaporator, because the radius of the inner bend of the elbow gradually decreases, the curvature becomes larger, the fluidity of the heat source decreases, and solidification is very easy to occur Risk of clogging. Contents of the invention [0004] The purpose of the present invention is to provide a single module of the heat absorber, which combines the physi...
